A Global Rarity Rank of G4 means: Apparently secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Intermittent streams are ephemeral waterways that serve as conduits only during particularly wet and rainy times of year. They are typically the uppermost reaches of stream systems. During spring snow melt and heavy rains, intermittent streams fill with water, draining the surrounding watershed, and transporting nutrients to the lower stream reaches. As with other ephemeral aquatic communities such as vernal pools, flora and fauna that inhabit intermittent streams are specially adapted for a wide range of hydrologic conditions. These communities can transition from being a coursing stream, to having remnant ponded sections, and then to being completely dry during a single growing season.

There are probably tens of thousands occurrences statewide. Intermittent streams are typically small and may be overlooked as streams after the water draws down. A few documented occurrences have good viability and are protected on public land or private conservation land. This community has statewide distribution, and includes several high quality examples. The current trend of this community is probably stable for occurrences on public land, or declining slightly elsewhere due to moderate threats related to logging in adjacent forests, recreational overuse by ATVs, and alteration to the natural hydrology. This community has probably declined moderately from historical numbers likely correlated with logging and development of the surrounding landscape.

The number and acreage of intermittent streams in New York have probably remained stable or have slightly declined in recent decades. Their relatively small size and seasonal hydroperiod may have contributed to the decline with many occurrences going undetected.
